Hello!

Could anybody tell me if it's possible to communicate simulated S7-1200 with HyperTerminal over TCP connection with TSEND_C and TRCV_C?

I try but cann't establish the connection, plc doesn't ping from external devices.

Hello,

no this is not possible.

The communication Interface in PLCSIM is internal and not accessible from external applications.

You can try with the 3rd party product NettoPLCSIM if you get the connection interface with Hyperterminal.

 I've found information about connection between HMI simulation and S7-1200. So as I understand it's possible only if I have S7-1200? I mean only one way?

the FAQ you linked talk about a real PLC an not a simulated PLC!

A simulated PLC use the virtual Interface PLCSIM to communicate with the Engineering or the HMI.

 So for communicate PLCSIM S7-1200 by TCP I have to use only Net2plcsim?

But is it possible to communicate this way with Hyperterminal or only with S7 HMI?

for HMI you don't need net2PLCSIM if the HMI is simulated on the same System, external HMI is not possible!

for Hyperterminal you should try to use net2PLCSIM

 Yes I try it but no success..

I try to communicate laptop (192.168.0.250) with PLCSIM S7-1200 (192.168.0.1)

and Hyperterminal at PC station (192.168.0.3)

I start Nettoplcsim and get port 102. Then I start my TIA project and Simulation. After I config Nettoplcsim for my plcsim and netcard ip addresses and start Nettoplcsim server.

Then I start Hyperterminal at PC station with connection via TCP to 192.168.0.250 and try to send one char from plcsim...nothing...and if I try to send anything from hyperterminal to plcsim it close the connection.

Does anybody tried to communicate this way?

I don't understand what I've missed..

I believe NetToPlcsim only works with 300/400 simulations. It does not currently work with 1200/1500 simulations.
